Volts
The default NetScan system units and resolution are dependent on the low or high volts range:
Low Range
Resolution
High Range
Resolution
±100 mV
3.12 µV/bit
±2.5 V
78.75 µV/bit
±1 V
31.21 µV/bit
±25 V
787.46 µV/bit
±5 V
156.06 µV/bit
±250 V
7.87 mV/bit
±10 V
312.12 µV/bit
The default binary format returns 2 bytes of 2’s complement binary data with the user selecting low/high byte or
high/low byte.
For Volts channels all ASCII readings will be of the form:
±XXX.XXXXXXX where X is an ASCII digit
Time/Date Stamp
Time/Date values have the following ASCII format:
hh:mn:ss.t,mm,dd,yy
hh:mn:ss.t,mm,dd,yy
hh:mn:ss.t,mm,dd,yy
Value
Description
Value
Description
hh (00< hh <23)
hour
mm (01< mm< 12)
month
mn (00< mn < 59)
minute
dd (valid by month)
day
ss (00< ss < 59)
seconds
yy (00 < yy < 99)
year
t (00< t < 9)
tenth of
seconds
Time/Date stamp output values occur within HLL and acquisition buffer output queries. Time/Date stamp
output values have the same ASCII format as Time/Date with exception of the fourth value. For Time/Date
stamp the value is mss (milli-seconds) where: (000< mss < 999).
An example:
01:25:20.600,2/28/97 = 20.6 seconds after 1:25 AM, on Feb. 28th, 1997
Scan Interval
Scan Interval formats have the following ASCII format:
hh:mm:ss.t
An example:
01:02:03.5 = Scan interval of 1 hour, 2 minutes and 3.5 seconds
